290 REPORTS ON THE STATE OF SCIENCE.—IQ1I3. 
Solid and leaded.—lf the types of consecutive 
lines are set with no vertical interval between the 
bodies, the type is ‘solid.’ When there is a vertical 
interval, say of a thirty-sixth of an inch, the type is 
‘two-point leaded.’ A large face type of ten-point 
body with two-point leading will produce about the 
same vertical space between the short letters as a 
small-face type of twelve-point body printed solid. 
An indentation occurs in a line where the print 
does not extend to the same length as in neigh- 
bouring lines, ¢.g., the first line of this paragraph.
